Kenmore Microwave F1 Error Code — Control Board Fault

Kenmore Microwave

High Severity
Warning: If your Kenmore appliance displays the F1 error code and you are unsure how to proceed, turn off the appliance and contact a qualified technician. Some errors require professional repair to avoid further damage or safety risks.

The F1 error code on a Kenmore microwave indicates the main control board has detected an internal fault. This error typically means the control board cannot reliably operate the microwave and has disabled it as a safety measure.

Causes

  • Failed or damaged main control board
  • Power surge damage to board components
  • Moisture or grease contamination of the board

What To Do

  1. Unplug the microwave for 5 minutes and restore power — some transient F1 errors will clear after a power reset.
  2. If F1 returns immediately, the control board requires professional replacement.
  3. Do not attempt to operate the microwave with a persistent F1 error.

Control board replacement is a common Kenmore microwave repair our technicians complete regularly.
